China's First Submarine Optical Cable

Mar. 30, 2020

On December 15, 1993, China ’s first Submarine Optical Cable, a total of 1252
kilometers of submarine optical cables, opened from Shanghai Nanhui to Miyazaki,
Kyushu, Japan. The total communication capacity of this submarine optical cable
system amounts to 7,560 communication circuits, which is equivalent to more than
15 times the Sino-Japanese submarine coaxial cable built in 1976. The opening of
China-Japan submarine optical cables has increased China's international
communications capacity by more than 80%.
